High-resolution MRI of Atrial Fibrillation Patients Prior to Focal Impulse and Rotor Modulation (FIRM) Ablation

January 24, 2020


The goal of the study is to find a correlation between FIRM targeted sites and micro-anatomic fibrotic tracks. Patients will first undergo a contrast-enhanced MRI scan to provide a 3-dimensional image of the left and right atria, and will then be observed using an MRI machine to determine the correlation.


Study Information

20 subjects will be enrolled in the study. The primary purpose of the trial is observation. The study began on November 3, 2016 and is estimated to be completed by November 3, 2020.


Inclusion Criteria


  • Patients who have symptomatic paroxysmal or persistent atrial fibrillation and are currently undergoing clinically-indicated ablation procedures utilizing FIRM mapping with pre-operative MRI.
  • Volunteers for the study must be at least 18 years of age.


Exclusion Criteria


  • LAA thrombus detected on pre-procedure TEE
  • Patient unable to receive MRI scan
  • Patient unable to receive gadolinium contrast



The study will take place at Ohio State University, Columbus, Ohio, United States, 43210. If you have any questions, please contact Adrianne Miller, RN at 614-685-4394 /, or Julie Ryan at 614-685-4394 /

The study is sponsored by the Ohio State University and directed by Deanna Golden-Kreutz, RN, Phd.
